* Add support for Imagination Technologies MetaJames Hogan2013-03-052-0/+264
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for Imagination Technologies Meta architecture (the architecture/ABI is usually referred to as metag in code). The Meta Linux kernel port is in the process of being upstreamed for v3.9 so it uses generic system call numbers. sys_lookup_dcookie writes a filename to buffer argument, so I've set TF flag. nfsservctl appears to be set to sys_ni_syscall in asm-generic/unistd.h so I've left it blank. truncate64/ftruncate64/pread64/pwrite64/readahead have unaligned 64bit args which are packed tightly on metag, so less arguments on metag. fchdir/llseek takes a file descriptor so s/TF/TD/ sync_file_range has 2 64bit args so uses 6 args, so s/4/6/ timerfd_create/msgget/msgctl/msgrcv/semget/segtimedop/semop/shmget/ shmctl/shmat/shmdt/recvmsg/migrate_pages have different number of args. oldgetrlimit is just getrlimit for metag. add TM flag to various memory syscalls. metag doesn't directly use sys_mmap_pgoff for mmap2. prlimit64/process_vm_readv/process_vm_writev take a pid so add TP flag. fanotify_init doesn't appear to take a file descriptor so remove TD.

* ARM: make it one-personality archDenys Vlasenko2013-02-215-22/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ARM in fact _is_ one personality. We had two personalities for it because it has a handful of syscalls with huge scnos (0x000f00xx). Extending syscall table to have [0x000f0005] index is of course not a good idea. Someone decided to handle that by having a separate personality just for these syscalls. But multi-personality arch does a bit more work in other parts. This patch is another alternative: "move" 0x000f00nn syscalls down to the entries just above last ordinary syscall, by manipulating scno if it falls into the 0x000f00xx range. In order to not worsen genuine undefined scnos' printing, the code remaps scno back to actual value before printing "syscall_NNN" string. * defs.h: Remove multi-reprsonality defines from ARM. * syscall.c (shuffle_scno): New function. (undefined_scno_name): New function. (get_scno): [ARM] Replace personality setting with scno shuffling. (trace_syscall_entering): Print unknown syscall name using undefined_scno_name().

* Clean up mmap decodingDenys Vlasenko2013-02-1918-33/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previous code merges too many similar, but different ways of decoding mmap. For example, sys_old_mmap is "params in memory" API... except SH[64], where it is "params in regs", i.e. what sys_mmap ("new mmap") function does on other arches! It's much simpler when every mmap handler has same API regardless of arch. Where API means whether params are in regs or in memory, and whether offset is in bytes, pages, or 4k blocks. Then we just insert correct function pointers into arch syscall tables. It turns out there are four common mmap APIs over all architectures which exist in Linux kernel, and one outlier for S390. A number of mmap decoders were plain wrong in arch tables. For example, BFIN has no old_mmap. It returns ENOSYS. I checked kernel sources for all arches nad fixed the tables. There was dead code for x86_64 for old_mmap: x86_64 has no old_mmap. * mem.c: Refactor mmap functions so that we have five mmap syscall handlers, each with the fixed API (not varying by arch). * pathtrace.c (pathtrace_match): Adjust sys_func == mmap_func checks. * linux/syscall.h: Declare new mmap syscall handler functions. * linux/arm/syscallent.h: mmap2 is sys_mmap_pgoff. * linux/avr32/syscallent.h: mmap is sys_mmap_pgoff. * linux/bfin/syscallent.h: old_mmap is ENOSYS, mmap2 is sys_mmap_pgoff. * linux/hppa/syscallent.h: mmap2 is sys_mmap_4koff. * linux/i386/syscallent.h: mmap2 is sys_mmap_pgoff. * linux/ia64/syscallent.h: mmap2 is sys_mmap_pgoff. * linux/m68k/syscallent.h: mmap2 is sys_mmap_pgoff. * linux/microblaze/syscallent.h: old_mmap is sys_mmap, mmap2 is sys_mmap_pgoff. * linux/mips/syscallent.h: mmap is sys_mmap_4kgoff. * linux/or1k/syscallent.h: mmap2 is sys_mmap_pgoff. * linux/powerpc/syscallent.h: mmap2 is sys_mmap_4kgoff. * linux/s390/syscallent.h: mmap2 is sys_old_mmap_pgoff. * linux/s390x/syscallent.h: mmap is sys_old_mmap and thus has 1 arg. * linux/sh/syscallent.h: old_mmap2 is sys_mmap, mmap2 is sys_mmap_4koff. * linux/sh64/syscallent.h: Likewise. * linux/sparc/syscallent1.h: mmap is TD|TM. * linux/tile/syscallent1.h: mmap2 is sys_mmap_4koff.

| | | | | | | | | sys_pwrite seems to do the same thing as sys_pwrite64 which we deleted when we removed non-Linux code. * linux/mips/syscallent.h: s/sys_pwrite64/sys_pwrite/ Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* Remove underscores from a few syscall names which have themDenys Vlasenko2012-03-1717-38/+38
| | | | | | | | | | | | | | | | | | | | Affected names are "_newselect", "_llseek", "_sysctl". I see no apparent reason why they have leading underscores. Moreover, some arches have underscored names and some have non-underscored ones. This is not consistent. I verified that every architectire I touched did not have a similarly named syscall without underscore, thus this change does not introduce new ambiquities. I left "_exit" untouched for now, but the same points stand for it too: some architectures use "exit" and no one complains. So why many arches are using "_exit"? * linux/*/syscallent.h: Remove underscores from displayed syscall names for _newselect, _llseek, _sysctl.

* alpha: fix decode of osf_sigprocmaskMike Frysinger2012-03-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The alpha sigprocmask syscall is special in that it comes from OSF rather than the style that everyone else uses. Tested with this simple code: $ cat test.c #include <signal.h> main() { sigset_t set, oldset; sigemptyset(&set); sigaddset(&set, SIGINT); sigaddset(&set, SIGHUP); sigprocmask(SIG_SETMASK, &set, &oldset); sigprocmask(SIG_UNBLOCK, &oldset, &set); sleep(3); } $ gcc test.c && ./strace ./a.out ... osf_sigprocmask(SIG_SETMASK, [HUP INT]) = 0 (old mask []) osf_sigprocmask(SIG_UNBLOCK, []) = 0x3 (old mask [HUP INT]) osf_sigprocmask(SIG_BLOCK, [CHLD]) = 0x3 (old mask [HUP INT]) ... * linux/alpha/syscallent.h: Call sys_sigprocmask for osf_sigprocmask, and change number of arguments to two. * signal.c (sys_sigprocmask): Fix decoding of alpha osf sigprocmask.
